Hubei Shenzi Technology has obtained AEC-Q102 automotive grade certification, defining a new benchmark for automotive grade UVC LED application scenarios
Recently, Wuhan Youweixin Technology Co., Ltd. (UVLEDTEK) has successfully passed the AEC-Q102 automotive grade certification for its independently developed ultraviolet UVC LED products, becoming a key technological breakthrough in the field of automotive grade ultraviolet semiconductors in China. This achievement not only signifies that the reliability and stability of Youweixin UVC LED products in the automotive electronics field have reached the international top level, but also means that Chinese enterprises are moving from "following" to "leading" in automotive grade UVC LED technology.
As a national level specialized and innovative "little giant" enterprise, Youweixin has already established a strict quality control system covering the entire industry chain. Based on the ISO 9001 quality management system certification, it passed the IATF 16949 international automotive industry quality management system certification as early as 2023. The passing of the AEC-Q102 certification further consolidates its leading position in the field of automotive electronic core components.
The urgent need for health protection in car cabins is highlighted UVC LED is the preferred sterilization technology
As cars gradually become the "third living space", enclosed cabins that are used for more than 2.5 hours a day are facing severe microbial pollution challenges. Data shows that the bacterial density on high-frequency contact surfaces such as the steering wheel and central control screen in the car can reach more than 5 times that of a toilet seat. After long-term use of the air conditioning system, the microbial concentration can increase by 300%. In the post pandemic era, consumers' attention to in car biosafety has significantly increased, and a healthy cabin has become a core consideration when purchasing a car. Youweixin UVC LED technology precisely destroys microbial DNA/RNA structures in the 265-280nm deep ultraviolet band, achieving an instantaneous sterilization rate of up to 99.9% against dozens of pathogens such as H3N2 influenza virus and Escherichia coli. Compared to traditional chemical disinfection methods, its advantages of no residue, 20000 hour long lifespan, and low power consumption make it the preferred solution for a healthy car cabin. Complete the air circulation sterilization of the entire vehicle in 15 minutes, and use automated start stop technology to achieve "clean on board". It has been favored by many car companies such as BYD and Chery and has become a standard for automotive brands.
Breakthrough in core technology,
Building a technological benchmark for automotive grade application scenarios
As one of the most stringent reliability standards in the field of automotive electronic components, AEC-Q102 certification covers rigorous testing conditions such as thermal shock at temperatures ranging from -40 ℃ to 100 ℃, live aging at high temperatures of 100 ℃, live aging in double 85 humid and hot environments, H2S/SO2/NO2/Cl2 corrosive gas testing, and 8000V discharge testing, ensuring stable operation of components under complex operating conditions for more than 10 years. With its core technology, Youweixin not only meets standards, but also achieves multiple breakthroughs.
03、High reliability packaging technology, breaking through the adaptability limit of automotive grade environments
By using aluminum nitride ceramic substrate packaging technology and optimizing the stress distribution of bonding wires through finite element analysis, the fatigue resistance of solder joints is improved by 60%. By using our proprietary patented technology for airtight packaging, combined with our exclusive UVC chip technology that can withstand high temperature and high humidity environments, the lamp beads have passed 1000 hours of 85 ℃/85% RH wet and hot live aging testing with zero failure and a protection level of IP67. At the same time, this airtight packaging technology can also pass automotive salt spray testing to ensure that the components are not damagedStable operation for over 10 years in various extreme environments, with technical parameters comprehensively exceeding AEC-Q102 certification requirements.
Three From technology leadership to ecological construction Embark on a new era of automotive health technology This certification marks the re establishment of scene definition rights for Chinese enterprises in the field of automotive grade UVC LED. The Uwai Core technology solution has achieved deep integration with the on-board ECU system of mainstream vehicle enterprises, supported the upgrading of OTA remote disinfection and sterilization strategy, and promoted the evolution of the health cockpit from a single hardware configuration to an intelligent protection system. According to industry predictions, the global penetration rate of UVC sterilization modules in new cars is expected to exceed 30% by 2025, and the penetration rate in the new energy vehicle market is expected to reach over 50%, forming a sub market of billions. As the only domestic supplier with the full industrial chain technology capability of UV LED, Youweixin is accelerating the layout of the collaborative disinfection and sterilization program of UVC LED and photocatalyst, developing customized modules for shared travel, high-end MPV and other subdivision scenarios, and promoting the upgrading of UVC LED technology from "functional modules" to "health and ecological core components". In the future, the company will rely on the dual quality systems of ISO 9001 and IATF 16949 to build a full lifecycle traceability system covering chip design, process control, and terminal applications, providing safer and more reliable automotive grade health solutions for global automakers.
